MECHANICAL STEPLESS GEAR Russian patent published in 2001 - IPC

FIELD: mechanical engineering. SUBSTANCE: stepless gear contains frictional multidisk transformer of the torque, frame 7 with rollers 6 and gearing differential. Driving disks 3 of the transformer are connected with driven disks 5 through rollers 6. Frame 7 of rollers 6 is connected with an automatic device for controlling the gear thorough link 8. The differential housing is driven by input shaft 2 of the gear through three pinions. One side pinion of the differential is connected with the shaft of the driven pinions, the other side pinion of the differential is connected with output shaft 15 of the gear. EFFECT: enhanced capacity and efficiency due to extending the range of the transmission ratio, stepless control down to the zero speed of the rotation of the output shaft and its reversing. 1 dwg
